For consistency, Fandom's Community Creation Policy states that we do not permit communities "whose main purpose is to represent a political party, advocate for or against a political ideology, or generally opine regarding political issues". I think the key word is "advocate". In CE in particular, "News event happened" conveys a very different message to start a conversation than "Political Party was Right Because News Event" happened.
I understand that there is still some ambiguity in that definition. As alluded to by many, "politics" these days is a terminology that is could be extended to many sorts of conversation in every day life. I don't think it's possible (or reasonable) to try to sit here and think of an all-encompossing definition.
But it's also good to be clear about what politics is not:
DToast and now myself endorse one of the moderator's (Uta) example on something that is not inherently political - (original: https://gamefaqs.gamespot.com/boards/11-team-gamefaqs/80747428/979919729):
"If a game has political theming it's of course fine to talk about that. I don't think anyone is going to be moderated for talking about the anti-capitalist themes of Final Fantasy VII. I don't think anyone is going to get moderated for talking about Wolfenstein either. As for that second comment. Anything that's say, a basic human right or even just a basic fact about reality? That's not political. Just because one particular group likes to make science and social denial their political points doesn't mean those things actually are politics. We're not going to go around moderating people for being Trans or talking about Trans issues "
To broaden it a little - Politics is not discussing political messages directly relating to video game gameplay/design, discussing how a video game incorporated a member of a tradtionally underrepresented group into the game, discussing how an element of your identity is or is not properly represented in a game. Our intention is to use a stringent definition of politics that covers clear trolling and flame wars, and not a loose definition to simply police speech.
Obviously, there is still intepretation in some of these definitions and examples, but common sense can be readily applied for 99% of the things not covered thus.
Well, I got some clarification on what constitutes politics, though tbh this raises more questions than it answers.
